Available in PDF, EPUB and Kindle. Book excerpt: Silicon (Si) is gaining increased attention in the farming sector because of its beneficial effects observed in several crop species, particularly under stress conditions. The magnitude of benefits is predominantly observed in plant species that can accumulate Si above a certain threshold. Therefore, deciphering the molecular mechanisms and genetic factors conferring a plant ability to take up silicon is necessary. Along these lines, several efforts have been made to identify the specific genes regulating Si uptake and distribution in plant tissues. This information finds its usefulness in identifying Si-competent species, and could eventually lead to improving this ability in low-accumulating species. The successful exploitation of Si in agriculture depends highly on the understanding of different Si properties including plant-available Si from the soil, transport within tissues, deposition in planta, and Si effect on different metabolic and physiological processes. In addition, a better comprehension of external factors influencing Si uptake and deposition in plant tissue remains important. A plant can take up Si efficiently only in the form of silicic acid and most soils, despite containing high concentrations of Si, are deficient in plant-available Si. Consequently, soil amendment with fertilizers rich in plant-available Si is now viewed as an affordable option to protect plants from the biotic and abiotic stresses and achieve more sustainable cropping management worldwide. Articles compiled in the present research topic touch upon several aspects of Si properties and functionality in plants. The information will be helpful to further our understanding of the role of Si and contribute to exploit the benefits plants derive from it.
Download or read book Soil Fertilizer and Plant Silicon Research in Japan written by Jian Feng Ma and published by Elsevier. This book was released on 2002-08-09 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon (Si) plays a significant role in the resistance of plants to multiple stresses including biotic and abiotic stresses. Silicon is also the only element that does not damage plants when accumulated in excess. However, the contribution of Si to plant growth has been largely ignored due to its universal existence in the earth's crust. From numerous intensive studies on Si, initiated in Japan about 80 years ago, Japanese scientists realized that Si was important for the healthy growth of rice and for stability of rice production. In a worldwide first, silicon was recognized as a valuable fertilizer in Japan. The beneficial effects of Si on rice growth in particular, are largely attributable to the characteristics of a silica gel that is accumulated on the epidermal tissues in rice. These effects are expressed most clearly under high-density cultivation systems with heavy applications of nitrogen. Si is therefore recognized now as an ''agronomically essential element'' in Japan.Recently, Si has become globally important because it generates resistance in many plants to diseases and pests, and may contribute to reduced rates of application of pesticides and fungicides. Silicon is also now considered as an environment-friendly element. The achievements of Si research in Japan are introduced in this book, in relation to soils, fertilizers and plant nutrition.
Download or read book Silicon in Plants written by Durgesh Kumar Tripathi and published by CRC Press. This book was released on 2016-12-08 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present era, rapid industrialization and urbanization has resulted in unwanted physiological, chemical, and biological changes in the environment that have harmful effects on crop quality and productivity. This situation is further worsened by the growing demand for food due to an ever increasing population. This forces plant scientists and agronomists to look forward for alternative strategies to enhance crop production and produce safer, healthier foods. Biotic and abiotic stresses are major constraints to crop productivity and have become an important challenge to agricultural scientists and agronomists due to the fact that both stress factors considerably reduce agriculture production worldwide per year. Silicon has various effects on plant growth and development, as well as crop yields. It increases photosynthetic activity, creates better disease resistance, reduces heavy metal toxicity, improves nutrient imbalance, and enhances drought tolerance. Silicon in Plants: Advances and Future Prospects presents the beneficial effects of silicon in improving productivity in plants and enhancing the capacity of plants to resist stresses from environmental factors. It compiles recent advances made worldwide in different leading laboratories concerning the role of silicon in plant biology in order to make these outcomes easily accessible to academicians, researchers, industrialists, and students. Nineteen chapters summarize information regarding the role of silicon in plants, their growth and development, physiological and molecular responses, and responses against the various abiotic stresses.
Download or read book Silicon and Plant Diseases written by Fabrício A. Rodrigues and published by Springer. This book was released on 2015-10-15 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon, considered to be the second most abundant mineral element in soil, plays an important role in the mineral nutrition of plants. A wide variety of monocot and dicot species have benefited from silicon nutrition, whether direct or indirect, when they are exposed to different types of abiotic and or biotic stresses. Besides the many agronomic and horticultural benefits gained by maintaining adequate levels of this element in the soil and also in the plant tissue, the most notable effect of silicon is the reduction in the intensities of a number of plant diseases caused by biotrophic, hemibiotrophic and necrotrophic plant pathogens in many crops of great economic importance. The aim of this book is to summarize our current understanding of the effects of silicon on plant diseases. The chapters address the dynamics of silicon in soils and plants; the history of silicon in the control of plant diseases; the use of silicon to control soil-borne, seed-borne and foliar diseases in monocots and dicots; the mechanisms involved in the host resistance against infection by plant pathogens mediated by silicon as well as the current knowledge at the omics level, and finally, highlights and prospects for using silicon in the future.

Book excerpt: Presenting the first book to focus on the importance of silicon for plant health and soil productivity and on our current understanding of this element as it relates to agriculture.Long considered by plant physiologists as a non-essential element, or plant nutrient, silicon was the center of attention at the first international conference on Silicon in Agriculture, held in Florida in 1999.Ninety scientists, growers, and producers of silicon fertilizer from 19 countries pondered a paradox in plant biology and crop science. They considered the element Si, second only to oxygen in quantity in soils, and absorbed by many plants in amounts roughly equivalent to those of such nutrients as sulfur or magnesium. Some species, including such staples as rice, may contain this element in amounts as great as or even greater than any other inorganic constituent. Compilations of the mineral composition of plants, however, and much of the plant physiological literature largely ignore this element. The participants in Silicon in Agriculture explored that extraordinary discrepancy between the silicon content of plants and that of the plant research enterprise.The participants, all of whom are active in agricultural science, with an emphasis on crop production, presented, and were presented with, a wealth of evidence that silicon plays a multitude of functions in the real world of plant life. Many soils in the humid tropics are low in plant available silicon, and the same condition holds in warm to hot humid areas elsewhere. Field experience, and experimentation even with nutrient solutions, reveals a multitude of functions of silicon in plant life. Resistance to disease is one, toleration of toxic metals such as aluminum, another. Silicon applications often minimize lodging of cereals (leaning over or even becoming prostrate), and often cause leaves to assume orientations more favorable for light interception. For some crops, rice and sugarcane in particular, spectacular yield responses to silicon application have been obtained. More recently, other crop species including orchids, daisies and yucca were reported to respond to silicon accumulation and plant growth/disease control. The culture solutions used for the hydroponic production of high-priced crops such as cucumbers and roses in many areas (The Netherlands for example) routinely included silicon, mainly for disease control. The biochemistry of silicon in plant cell walls, where most of it is located, is coming increasingly under scrutiny; the element may act as a crosslinking element between carbohydrate polymers.There is an increased conviction among scientists that the time is at hand to stop treating silicon as a plant biological nonentity. The element exists, and it matters.

This book was released on 2012-12-06 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: The publication of this book was undertaken with two purposes in view: to bring together informatian on the deposition by living organ isms of unique skeletal structures composed of amorphous silica, and to review recent data on the involvement of silicon in physiological and biochemical processes. Although widely varying viewpoints are represented, all the contributors are very interested in the events in volved in the formatian of siliceaus structures and their function. Data presented deal with these questions in a variety of plant and animal systems, and at levels ranging from the evolutionary to the biochemical and ultrastructural. Innovations in electron microscopy and, indeed, the advent of electron microscopy itself, have stimulated many ultra structural studies of silica deposition, work which has deepened and widened the interest in those organisms which routinely produce "glassy skeletons. " The question of how silicon participates in biological systems in volves a spectrum of fields that indudes the chemistry of silicon per se, its biogeochemistry, biochemistry, ecology, and so forth. In this book, however, attention is focused up on the biological aspects of silicon and siliceous structures, with emphasis on the evolutian, phylogeny, morphology, and distribution of siliceaus structures, on the cellular as peets of silica deposition, and on the physiological and biochemical roles of silicon. This volume represents the first compilatian of such data. Because such a variety of subjects and fields are covered, the reader will have to glean for himself some of the comparative aspects of the data.
Download or read book Silicon Biomineralization written by Werner E. G. Müller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: During evolution silica deposition has been used in Protozoa, Metazoa and in plants as skeletal elements. It appears that the mechanisms for the formation of biogenic silica have evolved independently in these three taxa. In Protozoa and plants biosilicification appears to be primarily driven by non-enzymatic processes and procedes on organic matrices. In contrast, in sponges (phylum Porifera) this process is mediated by enzymes; the initiation of this process is likewise dependent on organic matrices. In this monograph the role of biosilica as stabilizing structures in different organisms is reviewed and their role for morphogenetic processes is outlined. It provides an up-to-date summary of the mechanisms by which polymeric biosilica is formed. The volume is intended for biologists, biochemists and molecular biologists, involved in the understanding of structure formation in living organisms and will also be very useful for scientists working in the field of applied Nanotechnology and Nanobiotechnology.
